LIAPP Completes Preemptive Response to Android 17 'Cinnamon Bun' Beta
- Supports Stable LIAPP Service Operation Without Security Gaps Despite OS Changes
Lockin Company (CEO Myung-gyu Choi), a mobile app security specialist, announced that its app security service, LIAPP, has completed technical verification and support for the latest mobile operating system, Android 17 (codenamed Cinnamon Bun).
Android 17, the 17th major release of Android, first released as a beta version on February 12, 2026, features structural improvements across the entire system, including an enhanced UI based on Material 3 Expressive, seamless lens switching via a professional camera API, VVC (H.266) codec support, and Windows-based multitasking optimizations.
Major Android updates bring functional expansion and internal changes to the runtime, permission handling system, media framework, and background execution policy. These changes can potentially bypass existing security logic or cause unexpected crashes, making prior verification essential. Therefore, immediately after the beta release, LIAPP established a dedicated testing environment, inspected the stability of the protection engine in response to changes in the internal operation of ART (Android Runtime), and verified that execution integrity was maintained even in expanded camera and media API environments. Furthermore, we verified that security policies were consistently applied in multi-window and background execution environments, and conducted bypass scenario tests using the latest rooting and hooking tools (such as the Frida family). As a result, we confirmed that the existing protection policies operate reliably even in Android 17.
LIAPP is a no-code app security service that can be implemented without additional SDK development or source code modification. It is implemented by uploading app build artifacts (APK/AAB). It obfuscates code to complicate reverse engineering and detects and blocks app forgery and tampering attempts. It also identifies rooted and jailbroken environments, defends against debugging and memory tampering attacks, and detects and blocks hooking tools like Frida. Furthermore, execution integrity verification protects apps from modifications in normal environments. This structure provides substantial operational stability, as it maintains a security layer regardless of OS version changes without requiring additional development burden on developers.
Myung-kyu Choi, CEO of Lockin Company, stated, "Major Android updates can offer new user experiences while also expanding the attack surface. Especially for companies serving global clients, the speed of response to OS changes directly impacts trust." He emphasized, "LIAPP has been responding faster than anyone else by conducting structural analysis and attack scenario-based testing since the beta stage, enabling our clients to operate their services reliably and without security risks."
LIAPP has secured numerous clients with a high level of security sensitivity, including large fintech companies, global game publishers, and global big tech companies. These companies serve millions to hundreds of millions of users, and even a single security vulnerability that could occur immediately after an OS update can directly lead to massive financial losses and a decline in brand trust. For this reason, ensuring complete support for Android 17 goes beyond simple technical support and is a key task directly linked to our clients' business continuity. By proactively addressing the issue from the beta stage, LIAPP has enabled our clients to maintain stable services even during the OS transition. This demonstrates both our technological prowess and our speed of response as a mobile app security service provider.
This concludes.
